M&P 9C magazine release problem.

I have started carrying my M&P 9C inside my waistband. It fits okay but the magazine release button sticks out so far it is releasing the magazine while still in the waistband. Moved the release to the right side, same thing. This is not acceptable, but before I begin grinding off the button, is anyone having this problem and is anyone making a smaller or different release button. Or does anyone have a solution. The button moves easily and not very much to release the magazine.
I can grind it off, but it will look like hell.

I am not aware of any aftermarket substitutions for a magazine release button or spring. Perhaps someone else does.

Adjusting the magazine catch spring to increase its tension rather than modifying the magazine catch profile might be a suitable solution.

I have adjusted a few springs using both of the methods described below.

The "spring" that controls the tension on the button is a straight wire in the center of the magazine well on its forward surface. Its center-line location allows for ambidextrous spring tension.

This wire is similar to piano wire in its stiffness. It is press-fitted into a slightly smaller diameter hole in the polymer frame. The tension on the spring can be increased by slightly bending the wire incrementally to achieve the desired tension. The attached photo illustrates the spring in a M&P9 full size, however the MP9C is similar. To be an effective change the point of bending has to be low, down where the wire exits the frame. It can be bent in place with pliers, which is more difficult to do. The advantage of bending-in-place is that the correct orientation of the bend, i.e. directly to the right or left is easier to achieve.

The bend can be imparted with the wire out of the frame. It will take a good pull to remove the wire out of the frame; alternatively a fine punch can be used from below, see access hole in photo, and tap it out of the frame. Mark its visible position in the frame BEFORE removing it, to correctly install it. Once out of the frame, bending it is quite easy if you place it in a vise to choose the point of bending. After bending it, you will not be able to tap it back in, as it is bent !, so needle nose pliers to re-insert it to its proper depth and the bend lying flat across the magazine well.

Like all modifications, bend a little bit at a time to get desired tension. You don't want to over-bend then correct it as it will weaken the wire, thus the spring tension. It's a cheap part and a similar sized piano wire length / diameter can be used to replace it if you screw up.

The only modified mag release buttons I know of would magnify the problem since they extend the button.

Good idea mp9werks.

Dalealan, If you screw up the button they are in all likelihood an inexpensive part to replace. It might even be worth having a spare on hand before going any grinding. I'd check Brownells.

First off....Welcome to the Site!!

Being the internet, it's kind of hard to get a feel of what you mean by "The button moves easily and not very much to release the magazine."

All of the mag releases on my M&P's are what I consider fairly firm and it only takes about 1.5mm of depression to cause the mag to release.

Before I'd start grinding on the button I think I'd check around and see if I could buy one to have on hand in case I ground on it too much...which I most likely would!

If you have the abilities and want to try what mp9werks describes, he knows of what he speaks!

Personally, I think I'd call CS @ S&W and tell them, they'll probably send you a label to send it back to them so they can check it out.

What holster are you using, could it be a holster problem?

I think you should also check the holster. I have not had a problem with an M&P but have in the past with a 1911. If the holster is kydex you could remold that area so there is more room around the mag release. A second thought, could the mag release spring not be properly seated in the mag release button. It would still put some tension on the button by rubbing against it, just a stray thought.
Hope you get it worked out.

Sounds like it's a holster problem to me, your looking at the wrong area. Figure out what's wrong with your holster or get a new one that is properly designed. The Mp9c has been around a long time... haven't heard of any real issues with the mag release. What kind of holster do u have

Exactly.

Well designed holsters don't have any material contacting the mag release.

If your holster does; pick a better one.

I've been carrying pistols (both IWB and OWB) daily since 1987; and have never had a mag release from a holstered pistol.

I carry the 9c in Desantis inside the waist band holster. No issues, I would encourage you to find a new holster. Don't bend the spring or modify the gun until you are 100% sure it's the gun not the holster

I have release on the right side and with Raven holsters and Comp-Tac IWB, I simply ground away a small area (size of pencil eraser) of kydex where button touched.
